In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
If We [Really] Love Allaah, Then We Must Follow The Messenger
Allaah [The Most High] said:
[قُلۡ إِن كُنتُمۡ تُحِبُّونَ ٱللَّهَ فَٱتَّبِعُونِى يُحۡبِبۡكُمُ ٱللَّهُ وَيَغۡفِرۡ لَكُمۡ ذُنُوبَكُمۡۗ وَٱللَّهُ غَفُورٌ۬ رَّحِيمٌ۬ – Say (O Muhammad to mankind): ‘’If you (really) love Allah then follow me, Allah will love you and forgive you of your sins. And Allah is Oft-Forgiving, Most Merciful].’’ [Surah Aal Imraan Ayah 31]
This Ayah is conveyed to everyone who claims to love Allaah, whilst he is not one who truly follows Allaah’s Prophet Muhammad [sallal-laahu-alayhi-wasallam]- by obeying the Prophet’s command and keeping away from what he has forbidden. Therefore, unless he [i.e. the one who claims to love Allaah] truly follows the Messenger, then indeed he is not truthful in his claim [i.e. that he loves Allaah] [Ref 1]
Allaah [The Most High] also said: [قُلۡ أَطِيعُواْ ٱللَّهَ وَٱلرَّسُولَۖ فَإِن تَوَلَّوۡاْ فَإِنَّ ٱللَّهَ لَا يُحِبُّ ٱلۡكَـٰفِرِينَ – Say (O Muhammad): “Obey Allah and the Messenger (Muhammad).” But if they turn away, then Allah does not like the disbelievers]: Meaning: Say O Messenger [to the people]: Obey Allaah by following His Book [i.e. the Qur’aan], and obey the Messenger by following his Sunnah -whether you were present during his lifetime or present after he has passed away. [Surah Aali Imraan Ayah 32] [Ref 2]
Allaah [The Most High] also said: [يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُقَدِّمُوا بَيْنَ يَدَيِ اللَّهِ وَرَسُولِهِ ۖ وَاتَّقُوا اللَّهَ ۚ إِنَّ اللَّهَ سَمِيعٌ عَلِيمٌ – O you who believe! Do not put (yourselves) forward before Allah and His Messenger, and fear Allah. Verily! Allah is All-Hearing, All-Knowing. [يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَرْفَعُوا أَصْوَاتَكُمْ فَوْقَ صَوْتِ النَّبِيِّ – O you who believe! Raise not your voices above the voice of the Prophet..] [Surah Al-Hujuraat Aayaat 1 & 2]
When it is the case that Allaah forbade [them] from giving precedence to [themselves] over the Messenger, then which type of giving precedence to oneself over the Messenger [sallal-laahu-alayhi-wasallam] can be more severe than giving precedence to one’s intellect over the revelation he was sent with? Many of the Salaf have stated [that this ayah means]: ‘’Do not say anything [about the religion] until the Messenger speaks and do not act until he commands you.’’
The Most Disobedient Person Amongst The People Is That One Who Gives Precedence to His Intellect Or The Intellect of Another Person Over The Revelation The Messenger Was Sent With
The most disobedient person amongst the people and the most severe with regards to giving precedence to him over the Messenger is that one who gives precedence to his intellect or the intellect of another person over the revelation the Messenger was sent with. And when it is the case that Allaah has indeed forbidden them from raising their voices above the voice of the Messenger, then how about raising their intellects above the statements of the Messenger and the revelation he came with?! [Ref 3]

Disobedience to The Messenger Will Definitely Lead to Fitnah and Painful Torment
And Allaah (The Most High) said:
لَّا تَجۡعَلُواْ دُعَآءَ ٱلرَّسُولِ بَيۡنَڪُمۡ كَدُعَآءِ بَعۡضِكُم بَعۡضً۬اۚ قَدۡ يَعۡلَمُ ٱللَّهُ ٱلَّذِينَ يَتَسَلَّلُونَ مِنكُمۡ لِوَاذً۬اۚ فَلۡيَحۡذَرِ ٱلَّذِينَ يُخَالِفُونَ عَنۡ أَمۡرِهِۦۤ أَن تُصِيبَہُمۡ فِتۡنَةٌ أَوۡ يُصِيبَہُمۡ عَذَابٌ أَلِيمٌ
Make not the calling of the Messenger [Muhammad] among you as your calling of one another. Allah knows those of you who slip away under shelter [of some excuse without taking the permission to leave, from the Messenger]. And let those who oppose the Messenger’s [Muhammad] commandment [i.e. his Sunnah legal ways, orders, acts of worship, statements, etc.] [among the sects] beware, lest some Fitnah befall them or a painful torment be inflicted on them. [Surah An-Noor. Aayah 63]
[فَلۡيَحۡذَرِ ٱلَّذِينَ يُخَالِفُونَ عَنۡ أَمۡرِهِۦۤ -And let those who oppose the Messenger’s (Muhammad) commandment (i.e. his Sunnah, orders, acts of worship, statements) beware]; [أَن تُصِيبَہُمۡ فِتۡنَةٌ – lest some Fitnah befall them]: Meaning: [Lest] misguidance, calamity in the worldly life or disbelief[Ref a] befall them. [أَوۡ يُصِيبَہُمۡ عَذَابٌ أَلِيمٌ – or a painful torment be inflicted on them]: Meaning: Killed [i.e. by enemies] in the worldly life or punished in the hell fire in the afterlife. [Ref 1]
In these noble verses, Allaah [The Most High] commanded (us) to obey Him and His Messenger, and He made obedience to Him and His Messenger a means to happiness in this life and the next. And He forbade (us) from disobeying Him and His Messenger, and He made disobedience to Him and His Messenger a cause of punishment in this worldly life- a punishment [whose severity] cannot be perceived. And because of this Allaah ended these two verses by mentioning Fitnah [i.e. trial (as an indication of the)] severity of His Punishment and the painful torment (afflicted on) the one who disobeys Him and His Messenger.
Imaam Ahmad [rahimahullaah] said about this Ayah [i.e. Surah An-Noor. Aayah 63]: Do you know what Al-Fitnah is? Al-Fitnah is Shirk. Perhaps if he [i.e. the person] rejects some of his [i.e. the Prophet’s] statements, then something of deviation enters his heart, so he is destroyed. [Reported by Ibn Battah in Al-Ibaanah Al-Kubraa 97]
The punishments [that occur due to] sins and disobedience do vary depending on the level of the offences [committed] – sometimes the punishment occurs [as trial] in one’s religion and this is the greatest punishment. It is [when] the act of disobedience comes between a person and Imaan [Ref 2] and between him and Husnul khaatimah. [Ref 3]
If every single one of us scrutinizes himself attentively, he will find that whenever he commits a sin and fails to repent, he will realise that he did commit a greater sin than it previously. And the testimony to this is the saying of Allaah: [فَلَمَّا زَاغُوٓاْ أَزَاغَ ٱللَّهُ قُلُوبَهُمۡۚ –So when they turned away (from the Path of Allah), Allah turned their hearts away (from the Right Path)]
Allaah (The Most High) said:
وَنُقَلِّبُ أَفۡـِٔدَتَہُمۡ وَأَبۡصَـٰرَهُمۡ كَمَا لَمۡ يُؤۡمِنُواْ بِهِۦۤ أَوَّلَ مَرَّةٍ۬ وَنَذَرُهُمۡ فِى طُغۡيَـٰنِهِمۡ يَعۡمَهُونَ
And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly]. [6:110]
And Allaah (The Most High) said:
فَأَعۡقَبَہُمۡ نِفَاقً۬ا فِى قُلُوبِہِمۡ إِلَىٰ يَوۡمِ يَلۡقَوۡنَهُ ۥ بِمَآ أَخۡلَفُواْ ٱللَّهَ مَا وَعَدُوهُ وَبِمَا ڪَانُواْ يَكۡذِبُونَ
So He punished them by putting hypocrisy into their hearts till the Day whereon they shall meet Him, because they broke that (covenant with Allah) which they had promised Him and because they used to tell lies]. [9:77] [Ref 4]
[Ref a]: Takfeer and its principles:
Ref 1: Zaadul Maseer Fee Ilmit Tafseer’ By Imaam Ibnul Jawzi [rahimahullaah]
Ref 2: An act of disobedience comes between a person and Imaan: Imaam Sadi (rahimahullaah) stated about the Ayah: [وَاعْلَمُوا أَنَّ اللَّهَ يَحُولُ بَيْنَ الْمَرْءِ وَقَلْبِهِ – And know that Allah comes in between a person and his heart]- Therefore, beware of rejecting the command of Allaah when it comes to you at first, lest He comes between you and it [i.e. Allaah (The Most High) prevents you from guidance as a just recompense) when you turn away, for indeed Allaah intervenes between a person and his heart. Allaah causes it (i.e. the heart of a person) to change and turns it in any direction as He wills (i.e. as a just recompense for the one who rejects or turns away from the truth). Therefore, a slave (i.e. a Muslim) should increase in (uttering) the statement (i.e. the Du’aa): “O turner of the hearts, keep my heart firm upon your Religion; O turner of the hearts, turn my heart towards obedience to You.” [For further details, see Tayseer Al-Kareem Ar-Rahmaan Fee Tafseer Kalaam Al-Mannaan] [Also see Tafseer of this ayah in Al-Fawaa-id of Imaam Ibnul Qayyim (rahimahullaah) pages 140-144. Publishers: Maktabah Ar-Rushd. 3rd edition 2005]
[Ref 3]: Husnul Khaatimah: (i.e. It is when a Muslim leaves this world in obedience to Allaah and in obedience to Allaah’s Messenger; or leaves this world in a state confirmed to be a good end by textual proof. Imaam Albaani (rahimahullaah) stated some of these good signs in Ahkaam Al-Janaa-iz and from them: [a] The one who dies whilst uttering the Shahaadah; [b] The one who dies during the day or night on Friday; [c] Death by way of a plague, drowning etc; [d] The woman who dies during the period of post-natal bleeding as a result of giving birth; [e] death by fire; death through defending one’s wealth against a robber etc [See Ahkaam Al-Janaa’iz pages 21-24 –Shaikh Albaani (rahimahullaah) quotes the authentic ahaadeeth to establish these affairs and others]

We Can Never Be True Believers Until We Accept The Judgements of Allaah’s Messenger In Our Disputes
Allaah [The Most High] said:
وَمَآ أَرۡسَلۡنَا مِن رَّسُولٍ إِلَّا لِيُطَاعَ بِإِذۡنِ ٱللَّهِۚ
We sent no Messenger, but to be obeyed by Allah’s Leave [Surah An-Nisaa’ Ayah 64]
Allaah [The Most High] commanded and urged us to obey the Messenger and willingly submit to his path. He [The Most High] informed us that the purpose behind sending the Messengers is so that they are obeyed [and followed] in everything they command and keep away from everything they prohibited. This shows us that the Messengers are infallible in that which they convey from Allaah, command and prohibit, because Allaah commanded us to follow them unconditionally. Had it not been that they were infallible in that which they convey from Allaah’s and the fact that they never legislate anything [by themselves], then Allaah would not have commanded us to obey them unconditionally.
Also, Allaah [The Most High] said in Surah An-Nisaa Ayah 65:
فَلَا وَرَبِّكَ لَا يُؤۡمِنُونَ حَتَّىٰ يُحَكِّمُوكَ فِيمَا شَجَرَ بَيۡنَهُمۡ ثُمَّ لَا يَجِدُواْ فِىٓ أَنفُسِہِمۡ حَرَجً۬ا مِّمَّا قَضَيۡتَ وَيُسَلِّمُواْ تَسۡلِيمً۬ا
But no, by your Lord, they can have no Faith, until they make you (O Muhammad ) judge in all disputes between them, and find in themselves no resistance against your decisions, and accept (them) with full submission.
The people can never be true believers until they accept the judgements of Allaah’s Messenger in their disputes – in every affair about which they differ- except the issues of Ijmaa; because Ijmaa does not take place except based on evidence in the Qur’aan and authentic Sunnah. And it is not enough that people merely [and only] accept the judgements of the Messenger in that which they differ amongst themselves, rather there cannot be any resistance and reservation in their hearts after that judgement. It is not enough to merely demonstrate one’s acceptance; rather one has to submit wholeheartedly and willingly with a heart filled with ease about that judgement – in private and public.
Therefore, judging by what Islam has commanded without harbouring any reservations is a proof of one’s Eemaan-a proof of one’s obedience in fulfilling perfectly what he has been commanded and keeping away from what He has been forbidden. And whoever perfects these affairs, then indeed he has perfected all affairs related to his practice of the religion. And whoever abandons the Messenger’s judgement by not believing that it is the judgement that should be to be established, then he is an unbeliever. [Ref 1] As for the one who abandons it, but firmly believes that it is truth, then the judgement passed on him is similar to the one passed against the sinners who have not left the fold of Islaam.

Obedience to The Messenger Leads to Unity And Bidah Causes Splitting
Allaah [The Most High] said:
وَأَطِيعُواْ ٱللَّهَ وَرَسُولَهُ ۥ وَلَا تَنَـٰزَعُواْ فَتَفۡشَلُواْ وَتَذۡهَبَ رِيحُكُمۡۖ وَٱصۡبِرُوٓاْۚ إِنَّ ٱللَّهَ مَعَ ٱلصَّـٰبِرِينَ
And obey Allah and His Messenger, and do not dispute [with one another] lest you lose courage and your strength depart, and be patient. Surely, Allah is with those who are As-Saabireen [the patient ones, etc.]. [Surah Al-Anfaal Ayah 46]
[وَأَطِيعُواْ ٱللَّهَ وَرَسُولَهُ ۥ – And obey Allah and His Messenger]: Meaning: obey Allaah and the Messenger in that which you have been commanded, [and keep away from everything forbidden by Allaah and His Messenger], and adhere to this path in all circumstances.
[وَلَا تَنَـٰزَعُواْ – and do not dispute (with one another)]: Meaning: Do not dispute because it will cause your hearts to become disunited; [Ref 1] [فَتَفۡشَلُواْ – lest you lose courage]; [وَتَذۡهَبَ رِيحُكُمۡۖ – and your strength depart]: Meaning: [If you do not obey Allaah and His Messenger, and you start disputing], your resolve will depart. You will lose your strength and the promise you have been given that you will be aided -due to obedience to Allaah and His Messenger- will be withdrawn.
[وَٱصۡبِرُوٓاْۚ إِنَّ ٱللَّهَ مَعَ ٱلصَّـٰبِرِينَ – and be patient. Surely, Allah is with those who are As-Saabireen (the patient ones, etc.)]: Meaning: Exercise patience in obedience to Allaah [and obedience to His Messenger], for indeed Allaah will aid you and give you victory. Fear your Lord and humble yourselves to Him. [Source: (Tayseer al-kareem Ar-Rahmaan Fee Tafseer Kalaam Al-Mannaan). Abridged & slightly paraphrased]
[Ref 1]: Who causes disunity and disputes in the Ummah? Al-Allaamah Zaid Bin Haadi Al-Madkhali [may Allaah preserve him) said: ‘’The Mubtadi [the innovator] is the cause for the splitting (in the ummah); because splitting is connected to innovation and unity [upon the sound creed and methodology of the Salaf] is connected to the Sunnah. The obligation of refuting the Mukhaalif [the opposer of the truth] is not lifted from the scholar due to anticipation of harm, unless it is harm he is not able to bear. Then [in this case], Allah does not burden a soul beyond what it can bear. The earth is not devoid of people of knowledge who will carry out refutation against the Mubtadi and the Mukhaalif.” [Source: Al Ajwibah Al Mukhtasar Alaa As-ila Al-Ashrati(Page43-44)]
Al-Allaamah Saaleh Al-Fawzaan [may Allaah preserve him] said: The cause of the differences that take place between the callers is the differing in methodologies. And had the callers (may Allaah guide them and grant them success) traversed a singular methodology; and that is the methodology of the Messenger [sallal-laahu-alayhi-wasallam]– that which the Messenger (sallal-laahu-alayhi-sallam) and his companions were upon, then these differences would not have occurred. Therefore, it is obligatory upon all the callers to make their methodology one–upon the Book of Allaah and the Sunnah of the Messenger of Allaah (sallal-laahu-alayhi-wasallam); and that their call is (carried out) for the sake of Allaah and to make the word of Allaah uppermost. Their call should not be for the sake of desires, raising individuals or parties; rather their call should be sincerely for Allaah’s Face, to make Allaah’s word uppermost, to follow the Messenger of Allaah (sallal-laahu-alayhi-wasallam) and to aid his Religion. (So) by way of this the differences will cease.[Source:Al-Ijaabaatul Muhimmah Fil Mashaakil Al-Mulimmah (page:221-222)]

After Allaah and His Messenger Have Decreed a Matter, A Believer Should Not Have Any Other Option Outside This Decision
Allaah [The Most High] said:
وَمَا كَانَ لِمُؤۡمِنٍ۬ وَلَا مُؤۡمِنَةٍ إِذَا قَضَى ٱللَّهُ وَرَسُولُهُ ۥۤ أَمۡرًا أَن يَكُونَ لَهُمُ ٱلۡخِيَرَةُ مِنۡ أَمۡرِهِمۡۗ وَمَن يَعۡصِ ٱللَّهَ وَرَسُولَهُ ۥ فَقَدۡ ضَلَّ ضَلَـٰلاً۬ مُّبِينً۬ا
It is not for a believer, man or woman, when Allah and His Messenger have decreed a matter that they should have any option in their decision. And whoever disobeys Allah and His Messenger, he has indeed strayed in a plain error. [Surah al-Ahzaab Ayah 36]
Neither is it permissible nor befitting for the one attributed to Eemaan [to make any other choice] other than hastening to that which is pleasing to Allaah and His Messenger – fearing Allaah’s anger and the anger of Allaah’s Messenger, fulfilling what they have commanded and keeping away from what they have forbidden. It is neither befitting a male believer nor a female believer that when Allaah and His Messenger have decided a matter- Meaning: after Allaah and His Messenger have given a command regarding an affair, they should have no other choice as to whether that affair should be carried out or not; rather both a true male and female should know that the Messenger is more worthy to them than their ownselves. Therefore, they should not place some of their desires as an obstacle to the command of Allaah and His Messenger. [وَمَن يَعۡصِ ٱللَّهَ وَرَسُولَهُ ۥ فَقَدۡ ضَلَّ ضَلَـٰلاً۬ مُّبِينً۬- And whoever disobeys Allah and His Messenger, he has indeed strayed in a plain error].

The consequences of disobeying Allaah and His Messenger
The Believer Should Not Be Like Those Say, ‘’We Hear”, But They Hear Not
Allaah [The Most High]:
يَا أَيُّهَا الَّذِينَ آمَنُواْ أَطِيعُواْ اللّهَ وَرَسُولَهُ وَلاَ تَوَلَّوْا عَنْهُ وَأَنتُمْ تَسْمَعُونَ
وَلَا تَكُونُواْ كَٱلَّذِينَ قَالُواْ سَمِعۡنَا وَهُمۡ لَا يَسۡمَعُونَ
O you who believe! Obey Allaah and His Messenger, and turn not away from him [i.e. Messenger Muhammad] while you are hearing. And be not like those who say: “We have heard,” but they hear not. [Surah al-Anfaal Aayaat 20-21]
[يَا أَيُّهَا الَّذِينَ آمَنُواْ أَطِيعُواْ اللّهَ وَرَسُولَهُ – O you who believe! Obey Allah and His Messenger]: Meaning: [Obey Allaah and His Messenger] by fulfilling what they have commanded and keeping away from what they have forbidden. [وَلاَ تَوَلَّوْا عَنْهُ وَأَنتُمْ تَسْمَعُونَ – and turn not away from him (i.e. Messenger Muhammad) while you are hearing]: Meaning: Do not turn away from obedience to Allaah and obedience to His Messenger, whilst you are hearing what is been recited to you from the Book of Allaah [i.e. the Qur’aan, Allaah’s commands, admonitions and advices]- because turning away will place you in the most perilous situation. [وَلَا تَكُونُواْ كَٱلَّذِينَ قَالُواْ سَمِعۡنَا وَهُمۡ لَا يَسۡمَعُونَ – And be not like those who say: ‘’We have heard,’’ but they hear not]: Meaning: Do not suffice with claims that are devoid of reality, for it is something displeasing to Allaah and His Messenger. Eemaan is not wishful thinking and merely adorning oneself with it [outwardly]; rather it is that which firmly settles in the hearts and is affirmed by one’s deeds.

Consequences of disobeying Allaah and His Messenger
A Trait of The Munaafiqoon – [They Swear By Allaah Their Strongest Oaths That They Will Obey The Messenger, But They Intend Something Else
Allaah [The Most High] said:
وَأَقۡسَمُواْ بِٱللَّهِ جَهۡدَ أَيۡمَـٰنِہِمۡ لَٮِٕنۡ أَمَرۡتَہُمۡ لَيَخۡرُجُنَّۖ قُل لَّا تُقۡسِمُواْۖ طَاعَةٌ۬ مَّعۡرُوفَةٌۚ إِنَّ ٱللَّهَ خَبِيرُۢ بِمَا تَعۡمَلُونَ
قُلۡ أَطِيعُواْ ٱللَّهَ وَأَطِيعُواْ ٱلرَّسُولَۖ فَإِن تَوَلَّوۡاْ فَإِنَّمَا عَلَيۡهِ مَا حُمِّلَ وَعَلَيۡڪُم مَّا حُمِّلۡتُمۡۖ وَإِن تُطِيعُوهُ تَهۡتَدُواْۚ وَمَا عَلَى ٱلرَّسُولِ إِلَّا ٱلۡبَلَـٰغُ ٱلۡمُبِينُ
They swear by Allah their strongest oaths, that if only you would order them, they would leave [their homes for fighting in Allah’s Cause]. Say: ‘’Swear you not; [this] obedience [of yours] is known [to be false]. Verily, Allah knows well what you do.’’ Say: ‘’Obey Allah and obey the Messenger, but if you turn away, he [Messenger Muhammad] is only responsible for the duty placed on him [i.e. to convey Allah’s Message] and you for that placed on you. If you obey him, you shall be on the right guidance. The Messenger’s duty is only to convey [the message] in a clear way [i.e. to preach in a plain way].’’ [Surah an-Noor Aayaat 53-54]
Allaah [The Most High] informs us of the situation of those hypocrites who stayed behind and did not join the Messenger in Jihaad (Ref 1) – those in whose hearts there is a disease – that they swear by Allaah that if they are commanded in future to go out for Jihaad, they will do so; but Allaah rebutted them saying: [قُل لَّا تُقۡسِمُواْۖ -Swear you not]: Meaning: [Say to them O Muhammad], ‘’Neither are we in need of your oath nor your excuses, for indeed we have been informed about your affair and this obedience of yours is known to be false. This sluggishness and laziness of yours is known to us, even if you do not give an excuse. Therefore, your oath and excuse is nothing really; rather those in need of making an oath and an excuse are those whose affair is ambiguous, for maybe such excuse will benefit them and absolve them of blame. As for yourselves, then your excuses and oaths do not count; rather what is feared for you is Allaah’s punishment’’ and this is why Allaah said: [إِنَّ ٱللَّهَ خَبِيرُۢ بِمَا تَعۡمَلُونَ – Verily, Allah knows well what you do]: Meaning: Allaah will recompense you fully in accordance with this state of yours. As for the Messenger, his duty is only to give you commands and prohibitions, and this is why Allaah said: [قُلۡ أَطِيعُواْ ٱللَّهَ وَأَطِيعُواْ ٱلرَّسُولَۖ – Say: “Obey Allah and obey the Messenger]; [فَإِن تَوَلَّوۡاْ فَإِنَّمَا عَلَيۡهِ مَا حُمِّلَ وَعَلَيۡڪُم مَّا حُمِّلۡتُمۡۖ – but if you turn away, he (Messenger Muhammad) is only responsible for the duty placed on him (i.e. to convey Allah’s Message) and you for that placed on you]: Meaning: If you turn away from the message, then the Messenger has already conveyed it and you are held accountable. Your situation has manifested; your misguidance and deviation is clear, and you deserve punishment. [ وَإِن تُطِيعُوهُ تَهۡتَدُواْۚ – And if you obey him, you shall be on the right guidance]: Meaning: You will be guided to the straight path- in speech and deeds- and you have no other path to guidance except through obedience to Allaah and His Messenger. And without [obedience to Allaah and the Messenger], then it is impossible to be guided.
[وَمَا عَلَى ٱلرَّسُولِ إِلَّا ٱلۡبَلَـٰغُ ٱلۡمُبِينُ – The Messenger’s duty is only to convey (the message) in a clear way (i.e. to preach in a plain way)]: Meaning: He has clearly conveyed the message, therefore, neither is anyone to be in doubt nor in a state of ambiguity. The Messenger has clearly conveyed the message and Allaah is the only one who will call you to account and recompense you. The Messenger has no authority over reward or punishment after fulfilling his responsibility.

Consequences of disobeying the Messenger
The Messenger Suffices As The Only Perfect Example to Follow
Allaah [The Most High] said:
لَّقَدۡ كَانَ لَكُمۡ فِى رَسُولِ ٱللَّهِ أُسۡوَةٌ حَسَنَةٌ۬ لِّمَن كَانَ يَرۡجُواْ ٱللَّهَ وَٱلۡيَوۡمَ ٱلۡأَخِرَ وَذَكَرَ ٱللَّهَ كَثِيرً۬ا
Indeed in the Messenger of Allah (Muhammad) you have a good example to follow for him who hopes in (the Meeting with) Allah and the Last Day and remembers Allah much. [Surah Al-Ahzaab Ayah 21]
[لَّقَدۡ كَانَ لَكُمۡ فِى رَسُولِ ٱللَّهِ أُسۡوَةٌ حَسَنَةٌ۬ – Indeed in the Messenger of Allah (Muhammad) you have a good example to follow]: Meaning: [A perfect] righteous example; [لِّمَن كَانَ يَرۡجُواْ ٱللَّهَ وَٱلۡيَوۡمَ ٱلۡأَخِرَ – for him who hopes in (the Meeting with) Allah and the Last Day]: Ibn Abbaas said, ‘’For the one who hopes for Allaah’s reward and the bliss [He has kept for His slaves in the Afterlife]. [وَذَكَرَ ٱللَّهَ كَثِيرً۬ا – and remembers Allah much]: Meaning: Remembers Allaah a lot, because the one who truly remembers Allaah is that one who obeys Allaah’s commands [and keeps away from what He has forbidden] unlike the one who is heedless of his Lord. [Ref 1]
Allaah [The Most High] said:
إِنَّمَا كَانَ قَوۡلَ ٱلۡمُؤۡمِنِينَ إِذَا دُعُوٓاْ إِلَى ٱللَّهِ وَرَسُولِهِۦ لِيَحۡكُمَ بَيۡنَهُمۡ أَن يَقُولُواْ سَمِعۡنَا وَأَطَعۡنَاۚ وَأُوْلَـٰٓٮِٕكَ هُمُ ٱلۡمُفۡلِحُونَ
وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُ ۥ وَيَخۡشَ ٱللَّهَ وَيَتَّقۡهِ فَأُوْلَـٰٓٮِٕكَ هُمُ ٱلۡفَآٮِٕزُونَ
The only saying of the faithful believers, when they are called to Allah (His Words, the Qur’an) and His Messenger, to judge between them, is that they say: “We hear and we obey.” And such are the prosperous ones. And whosoever obeys Allah and His Messenger, fears Allah, and keeps his duty (to Him), such are the successful ones. [Surah An-Noor Aayaat 51-52]
The true believers are those whose actions testify to the truthfulness of their Eemaan when they are called to the [Book of] Allaah and the authentic Sunnah of Allaah’s Messenger to judge between them – whether it agrees with what they desire or not; for [when they called to that judgement] they say: [سَمِعۡنَا وَأَطَعۡنَاۚ -We hear and we obey]: Meaning: We have heard the judgement of Allaah and that of His Messenger; we respond to the one who call us to it and we obey it wholeheartedly without any reservation. Then Allaah [The Most High] said: [وَأُوْلَـٰٓٮِٕكَ هُمُ ٱلۡمُفۡلِحُونَ – And such are the prosperous ones].
Then Allaah [The Most High] said:
[وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُ ۥ وَيَخۡشَ ٱللَّهَ وَيَتَّقۡهِ فَأُوْلَـٰٓٮِٕكَ هُمُ ٱلۡفَآٮِٕزُونَ – And whosoever obeys Allah and His Messenger, fears Allah, and keeps his duty (to Him), such are the successful ones]. [Ref 2]
NB: Regarding the sin of judging by other than the judgement of Allaah and His Messenger, see links:

Imam ibnul Qayyim [rahimahullaah] said:
Muhammad’s [sallal-laahu-alayhi-wasallam] Ummah is not in need of anyone after him; rather the only need they have is someone to convey what he came with. Muhammad’s [sallal-laahu-alayhi-wasallam] message is comprehensive, universal and preserved. This universality, comprehensiveness and preservation is not limited to [any time and place], rather it is comprehensive for those to whom Muhammad [sallal-laahu-alayhi-wasallam] was sent [i.e. the whole world] and likewise with regards to everything that is needed in the fundamental and subsidiary issues of the religion.
Muhammad’s [sallal-laahu-alayhi-wasallam] message is sufficient, all embracing and universal- nothing else is needed besides it. It has not isolated any affair of truth needed by his Ummah in their sciences and deeds.
The Messenger of Allaah [sallal-laahu-alayhi-wasallam] did not leave this world until he acquainted his Ummah with everything. He even taught them the etiquettes of using the toilet; the etiquettes of sexual relations; the etiquettes of sleep and after waking up; the etiquettes of eating, drinking and travel.
He acquainted them with the etiquettes of speech and silence; the etiquettes of keeping company with the people and seclusion. He acquainted them with the affairs of illness, good health, poverty and wealth. He acquainted them with all the affairs of life and death.
He described Allaah’s throne, the angels, the jinn, the hell fire and the day of judgement in such a manner as if one has seen them with the naked eye. He [sallal-laahu-alayhi-wasallam] informed them about their Lord and His Perfect Names and Attributes, and that Allaah alone is their true object of worship.
He acquainted them with the Prophets of old and their nations – the events that took place between them and their nations – in such a manner as if one was present at that time. He acquainted them with all the means to good and the paths of evil- in general and in detail- which no other prophet informed his nation. He acquainted them with death and what will take place in the grave – either bliss or punishment.
He acquainted them with the evidences and proofs of Tawheed [i.e. the oneness of Allaah in His Lordship, Names and Attributes, and that Allaah alone has the right to be worshipped].
He acquainted them with Prophet hood and the affairs of the Afterlife, and he refuted all the sects of disbelief and misguidance. He acquainted them with war strategies- how to confront the enemy, the way to achieve victory and conquests. If only they knew and understood these affairs in the correct manner [i.e. the manner it should be understood], they would not be overcome by their enemy.
He acquainted them with the plots of Iblees and the ways through which he approaches them, and the ways to repel those plots and plans. He acquainted them with the soul- its characteristics and faults- in such a manner that they are not in need of anyone else to tell them about it.
He taught them how to live their daily lives and had they acknowledged and acted upon this, their worldly affairs would be firmly established. He brought them all the means of success in this life and the next, and they do not need anyone besides him.
So how can it be said that the path of Muhammad [sallal-laahu-alayhi-wasallam] is in need of something else outside of it. The reason for such a claim is due to the weak and little understanding of a person. Allaah [The Most High] said:
أَوَلَمْ يَكْفِهِمْ أَنَّا أَنزَلْنَا عَلَيْكَ الْكِتَابَ يُتْلَىٰ عَلَيْهِمْ ۚ إِنَّ فِي ذَٰلِكَ لَرَحْمَةً وَذِكْرَىٰ لِقَوْمٍ يُؤْمِنُونَ
Is it not sufficient for them that We have sent down to you the Book (the Qur’an) which is recited to them? Verily, herein is mercy and a reminder (or an admonition) for a people who believe. [29:51]
Allaah [The Most High] said:
وَنَزَّلْنَا عَلَيْكَ الْكِتَابَ تِبْيَانًا لِّكُلِّ شَيْءٍ وَهُدًى وَرَحْمَةً وَبُشْرَىٰ لِلْمُسْلِمِينَ
And We have sent down to you the Book (the Qur’an) as an exposition of everything, a guidance, a mercy, and glad tidings for those who have submitted themselves (to Allah as Muslims). [16:89]
Allaah [The Most High] said:
يَا أَيُّهَا النَّاسُ قَدْ جَاءَتْكُم مَّوْعِظَةٌ مِّن رَّبِّكُمْ وَشِفَاءٌ لِّمَا فِي الصُّدُورِ وَهُدًى وَرَحْمَةٌ لِّلْمُؤْمِنِينَ
O mankind! There has come to you a good advice from your Lord [i.e. the Qur’an, ordering all that is good and forbidding all that is evil], and a healing for that [disease of ignorance, doubt, hypocrisy and differences, etc.] in your breasts, – a guidance and a mercy [explaining lawful and unlawful things, etc.] for the believers. [10:57] [Ref 1:]
The Correct Manner In Which We Should Approach The Contemporary Sciences
Indeed, that which is stated by the astronomers about the celestial bodies, their sizes and the distance between them, and that which is said about the earth [i.e. by the geologists etc] is categorized into three affairs:
 That which is backed by the sound knowledge-based proofs [i.e. the Sharee’ah], therefore it is accepted.
 That which the knowledge-based proofs [i.e. the sharee’ah] declares to be false, therefore it is rejected.
 That which there is no proof to either accept or reject it, therefore it is unproven until a person from the people of knowledge [i.e. upright scholars of Ahlus Sunnah] examines it [i.e. examines what it indicates based on the Book and Sunnah] to show whether it should be accepted or rejected. As for accepting it without [sound] investigation and observation, but merely accepting it by blindly following them [i.e. the astronomers, geologists etc], then this is impermissible because of the numerous mistakes that occur as a result of that, and speaking -without knowledge – about Allaah and that which He has created [i.e. the entire universe and all that is within it]. [Ref 2]
